Transport Layer Security Wikipedia. Transport Layer Security TLS and its predecessor, Secure Sockets Layer SSL, are cryptographic protocols that provide communications security over a computer network. Several versions of the protocols find widespread use in applications such as web browsing, email, Internet faxing, instant messaging, and voice over IP Vo. IP. Websites are able to use TLS to secure all communications between their servers and web browsers. The Transport Layer Security protocol aims primarily to provide privacy and data integrity between two communicating computer applications. When secured by TLS, connections between a client e. The connection is private or secure because symmetric cryptography is used to encrypt the data transmitted The keys for this symmetric encryption are generated uniquely for each connection and are based on a shared secret negotiated at the start of the session see TLS handshake protocol The server and client negotiate the details of which encryption algorithm and cryptographic keys to use before the first byte of data is transmitted see Algorithm below The negotiation of a shared secret is both secure the negotiated secret is unavailable to eavesdroppers and cannot be obtained, even by an attacker who places themselves in the middle of the connection and reliable no attacker can modify the communications during the negotiation without being detected The identity of the communicating parties can be authenticated using public key cryptography. This authentication can be made optional, but is generally required for at least one of the parties typically the server The connection ensures integrity because each message transmitted includes a message integrity check using a message authentication code to prevent undetected loss or alteration of the data during transmission. In addition to the properties above, careful configuration of TLS can provide additional privacy related properties such as forward secrecy, ensuring that any future disclosure of encryption keys cannot be used to decrypt any TLS communications recorded in the past. TLS supports many different methods for exchanging keys, encrypting data, and authenticating message integrity see Algorithm below. As a result, secure configuration of TLS involves many configurable parameters, and not all choices provide all of the privacy related properties described in the list above see authentication and key exchange table, cipher security table, and data integrity table. Attempts have been made to subvert aspects of the communications security that TLS seeks to provide and the protocol has been revised several times to address these security threats see Security. Developers of web browsers have also revised their products to defend against potential security weaknesses after these were discovered see TLSSSL support history of web browsers. The TLS protocol comprises two layers the TLS record protocol and the TLS handshake protocol. TLS is a proposed Internet Engineering Task Force IETF standard, first defined in 1.

March 2. It builds on the earlier SSL specifications 1. Netscape Communications4 for adding the HTTPS protocol to their Navigator web browser. DescriptioneditClient server applications use the TLS protocol to communicate across a network in a way designed to prevent eavesdropping and tampering. Since applications can communicate either with or without TLS or SSL, it is necessary for the client to indicate to the server the setup of a TLS connection. One of the main ways of achieving this is to use a different port number for TLS connections, for example port 4. HTTPS. Another mechanism is for the client to make a protocol specific request to the server to switch the connection to TLS for example, by making a STARTTLS request when using the mail and news protocols. Once the client and server have agreed to use TLS, they negotiate a stateful connection by using a handshaking procedure. The protocols use a handshake with an asymmetric cipher to establish not only cipher settings but also a session specific shared key with which further communication is encrypted using a symmetric cipher. During this handshake, the client and server agree on various parameters used to establish the connections security The handshake begins when a client connects to a TLS enabled server requesting a secure connection and the client presents a list of supported cipher suites ciphers and hash functions. From this list, the server picks a cipher and hash function that it also supports and notifies the client of the decision. The server usually then provides identification in the form a digital certificate.

The certificate contains the server name, the trusted certificate authority CA that vouches for the authenticity of the certificate, and the servers public encryption key. The client confirms the validity of the certificate before proceeding. To generate the session keys used for the secure connection, the client either. DiffieHellman key exchange to securely generate a random and unique session key for encryption and decryption that has the additional property of forward secrecy if the servers private key is disclosed in future, it cannot be used to decrypt the current session, even if the session is intercepted and recorded by a third party. This concludes the handshake and begins the secured connection, which is encrypted and decrypted with the session key until the connection closes. If any one of the above steps fails, then the TLS handshake fails and the connection is not created. TLS and SSL do not fit neatly into any single layer of the OSI model or the TCPIP model. TLS runs on top of some reliable transport protocol e. TCP,9 which would imply that it is above the transport layer. It serves encryption to higher layers, which is normally the function of the presentation layer.
